Pre-heat the oven to 375 and line a sheet tray with a silicone mat. Put the pretzels into a zip top bag and use a rolling pin to completely crush them into crumbs. Then combine the mustard, honey, salt, dried onion, dried tarragon and smoked paprika in a large, shallow bowl. Take the chicken tenders and dredge each of them through the mustard mixture to coat them before transferring them into the bag of crumbs. When all of the chicken is coated and in the bag of crumbs, close the bag and give it a good shake to make sure the chicken is well crusted in the pretzels. Place the chicken on the prepared sheet tray and bake it for 30 minutes. Serve immediately and enjoy!
